a3e02fdaff With non-blocking collectives, a "round schedule" could fall on any address
alignment, which typically causes problems on SPARC.  Further, the pointer
manipulation to access elements in a round schedule was clumsy.  This change
introduces macros to facilitate addressing and make it more portable.

58413fa1e4 * properly setup communication infrastructure for libnbc.
* Prevent infinite recursion in progress loop.

Should fix improper barrier eugene was seeing.

0b887ab5a1 * Remove unneeded prototype that was causing compile issues anyway
* Use proper tag space (the negatives below the blocking communicators)
  instead of the point-to-point space
* Use the PML interface instead of the MPI interface, since the MPI
  interface 1) shouldn't be used by components and 2) doesn't like
  negative tags

6b22641669 added LibNBC (http://www.unixer.de/NBC) as collv1 (blocking) component.
I know it does not make much sense but one can play around with the
performance. Numbers are available at http://www.unixer.de/research/nbcoll/perf/.
This is the first step towards collv2. Next step includes the addition
of non-blocking functions to the MPI-Layer and the collv1 interface.

It implements all MPI-1 collective algorithms in a non-blocking manner.
However, the collv1 interface does not allow non-blocking collectives so
that all collectives are used blocking by the ompi-glue layer.

I wanted to add LibNBC as a separate subdirectory, but I could not
convince the buildsystem (and had not the time). So the component looks
pretty messy. It would be great if somebody could explain me how to move
all nbc*{c,h}, and {hb,dict}*{c,h} to a seperate subdirectory.

It's .ompi_ignored because I did not test it exhaustively yet.
